Bristol Palin: Engaged to Levi Johnston!

The 19-year-old daughter of Sarah Palin and her 20-year-old beau told Us Weekly exclusively about their plans to get married – and revealed that even Sarah didn’t know about the engagement until now!

“It felt right, even though we don’t have the approval of our parents,” Bristol said. “It is intimidating and scary just to think about what her reaction is going to be. Hopefully she will jump on board.”

Bristol and Levi were previously engaged but broke it off just after son Tripp was born in December of 2008.

UPDATE: Sarah issued a statement to NBC News, saying, “Bristol at 19 is now a young adult. We obviously want what’s best for our children. Bristol believes in redemption and forgiveness to a degree most of us struggle to put in practice in our daily lives.”

Bristol told People, “With [my mother], [Levi's] actions will have to speak louder than words. And he’ll have to get his education and a job and be willing to support Tripp the right way. And then I think she’ll come around.”
